moquette-io
java.lang.ClassNotFoundException: org.eclipse.moquette.spi.impl.subscriptions.Subscription in Android
Expected behavior
I used moquette broker already on android within an Unity application and it worked fine.
Now I have to write a native android app acting as an mqtt broke.
Actual behavior
It crashes with an ClassNotFoundException on startServer
Steps to reproduce
I am using following dependencies:
compile 'io.moquette:moquette-netty-parser:0.8.1' compile 'io.moquette:moquette-broker:0.8.1' compile 'io.moquette:moquette-parser-commons:0.8.1' compile 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.1.0' compile 'org.eclipse.paho:org.eclipse.paho.android.service:1.1.1'
OnCreate I start the server as following after checking all permissions:
`server = new Server();
MemoryConfig memoryConfig = new MemoryConfig(new Properties());
memoryConfig.setProperty(BrokerConstants.PERSISTENT_STORE_PROPERTY_NAME, Environment.getExternalStorageDirectory().getAbsolutePath()+ File.separator + BrokerConstants.DEFAULT_MOQUETTE_STORE_MAP_DB_FILENAME);
try {
server.startServer(memoryConfig);
//server.startServer();
} catch (IOException e) {
e.printStackTrace();
}`
Hi @mstranne which version of moquette are you using? since version 0.10 moquette in in the namespace io.moquette and not org.eclipse.moquette. Only the latest version of moquette is supported.
As you can see above, I am using version 0.8.1, so then the Error is even more confusing
Ok I changed the broker version to 0.12.1
Then I also had to change
memoryConfig.setProperty(BrokerConstants.PERSISTENT_STORE_PROPERTY_NAME, Environment.getExternalStorageDirectory().getAbsolutePath()+ File.separator + BrokerConstants.DEFAULT_MOQUETTE_STORE_MAP_DB_FILENAME);
to
memoryConfig.setProperty(BrokerConstants.PERSISTENT_STORE_PROPERTY_NAME, Environment.getExternalStorageDirectory().getAbsolutePath()+ File.separator + BrokerConstants.DEFAULT_MOQUETTE_STORE_H2_DB_FILENAME);
and now I get following error on startServer:

I don't have too much experience with Android, giving a look at stacktrace seems like that Android didn't find something, but probably the stack trace is more wide than you posted

could you solve it ?
I switched to mosquitto, building it as a c library, which can be used crossplattform

do you have any tutorial for that? my aim is to run mqtt broker (moquette) inside an android app
Hi @necoicould thank's for reporting it, in order to investigate it:
- could you describe better how to create a reproducer?
- could you reproduce it outside of Android environment?
- which Moquette version are you using?
